ADJUSTABLE HEADLIGHT.

APPLICATION FILED FEB.4, 1908.

i To 'al l 'whoni a-mwy concern: Y

itjknownthat I, IsAIA' 'D. MoMA-nNAirr', 1tizen. of the-. United States}residing at; 'Botkinsy' the county of; Shelby and State of Ohio,.'-ha've invented a new, and useful Adwrest-masts rin ii nrirqn'rb 1sa specification;

Th1s'finv'e'r'1tioh relates to -adjustable headglxg-hts"for'locomotives; electric cars,- etc., its 0 'ject' {heing'toprovide an attachment of; "fth'i'scharaeter so constructed and-arrangedthat whenthecar is' traveling-upon a-curved K-track the lamp will beshifted so as to direct .the lightalong the" track. i v

; Anotherobject is. to provide "an "attach ment of this character whichis simple, and Jdurable'in construction, can be readily con-' -necte d"to a car; and which is positive in op-' '--eratiOn.-' .2

mounted a centrally fulcrumed lever 12.

.Brack etsw13 extend transversely within the bracket 10 and below lever12 and are bolted" "to the bottompf the car body, thesebrackets 13serving to support the adjoining lever 12 at points removedfrom thepivot thereof." The' bracketflO in addition to its function as a'supiport'forthe pivot bolt 11 also acts as a. guar :for the lever 12 aswould be apparent by referring to Figs. 2 and 4.

, Wrist pins 14 extend from the end portions of lever 3 and pivotallymounted upon them are links 15 which are also connected to wrist pinsextending from. the end portions of lever 1 2; These wrist pins 16 alsoconstitute connections for draw bars17 the rear ends of which ares crewthreaded as at 18 and .=p roject into frames 19 from which hooks 2.0extend. These hooks are secured to slidable -rods'2'1 movably mountedwithin the frames and-having heads 22 connected to them .and within theframes. Springs 23 are mounted on the rods between the heads 22- and oneend of each frame and serveto hold the hooks 'normaily in position closeto the frames. These hooks engage the end portions of a chain 24, said.chain being held against acci dental detachment from the hooks by means.of spring retainers 25. Itwill be seen that the springs 23' by exertinga constant pull upon the hooks 2Q serve to hold the chain 2 1.

the-light raysalong the track in the usual manner. .W'hen, however, thecar travels along a curve the relation between the truck and car .bodywill be changed and the sprocket 1' upon turning relatively to the bodyAwill operate the chain so as to pull upon one or the other of the drawbars 17 and thus actuate the lever 12 This lever in turn operatesthe-links 1-5 and lever3 so as to :partlyrotatethe stem 5 and cause thelamp 9 to turn so as-to throw the light in the direction .in whichthe-par is moving. Although the paratush'asbeen shown a'sfapplied'toa pasenger'car such as. used in electr c ra lways and the like'it isto beunderstood t hat1fpre-.- I-f'errefdthe apparatus canalso be used-upon alocomotive withoutrequiring any material changes in the constructiondisclosed. By providing the two levers 3 and 12 it becomes possible tomake them comparatively short so that the front portion of the mechanismwill occupy a comparatively narrow space. The draw bars 17 and the chainMean of course pull along diverging lines to actuate the mechanism.Instead ofutilizing the lever 3 and links 15, a sprocket wheel 26 may besecured to stem 5 and a chain 27 placed in engagement therewith. Theends of the chain can then be attached to the ends of lever. 12 or tothe bars 17. This construction has been shown in Fig. 6.

What is claimed is:

1. The combination with a car body and a truck; of a toothed'wheelsecured to the truck and movable therewith, a stem ournaled upon the carbody, lamp engaging means carried thereby, a lever secured to thestem-and disposed below the body, supporting brackets therefor, anintermediate lever fulcrumed below the body, supporting an axguardbrackof a lamp supporting element mounted to partly rotaterelatively to the car aody, a flexible device extending around andengaging the wheel, a lever fulcrumed on. the car body, connectionsbetween the lever and the lamp supporting element, draw bars pivot--ally connected to the lever, and elastic con nections between said drawbars and the ends of the flexible device.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
